which jar contains a mixture?\n a jar of solid carbon\n a jar of carbon dioxide gas\n a jar of liquid copper\n a jar of copper and water
Answer
# Answer:
a jar of copper and water
# Explanation:
## Step1: Recall the definition of a mixture
A mixture is a combination of two or more substances that are not chemically combined.
## Step2: Analyze each option
- A jar of solid carbon: Carbon is an element, so it is a pure substance, not a mixture.
- A jar of carbon dioxide gas: Carbon dioxide ($CO_2$) is a compound (a pure substance formed by chemical combination of carbon and oxygen), not a mixture.
- A jar of liquid copper: Copper is an element, so it is a pure substance, not a mixture.
- A jar of copper and water: Copper (a solid metal) and water (a liquid compound) are two different substances that are not chemically combined. So this is a mixture.
